3Com 3C16670 - LinkBuilder FMS II Hub Configuration Manual page 7

Expansion modules connect
directly to the LinkBuilder MSH
coax or fiber Ethernet modules.
These expansion modules reduce
connectivity costs and easily
accommodate diverse cabling
requirements. Similarly, the 7-port
UTP module features six RJ-45
ports and a transceiver interface
port for connection to the backbone.
Small Satellite Office
Highlights
The smaller satellite office is not
expected to grow, but users need to
share data and access resources at
the central site. With its built-in
SmartAgent intelligence and optional
local bridging, the 8-port LinkBuilder
TP/8i fixed-port hub is a robust,
affordable solution.

Security: Defending
Data and Resources
The LinkBuilder FMS II hubs and the
Ethernet modules in the LinkBuilder MSH
support 3Com's LAN Security Architecture
(LSA), making them highly effective tools
for safeguarding valuable data and com-
puting resources. A patented, chip-based
system, LSA provides the following power-
ful security features:
• Need to Know protects sensitive data
on the network by checking destination
addresses on each packet and sending
readable packets only to authorized
nodes.
• Disconnect Unauthorized Device auto-
matically records and/or disables an
unauthorized device attempting to log
on to the network.
• Audit Log gives the manager a
complete record of user and device
changes on the network.
• Multiple User Levels ensure that only
authorized users have access to
critical network functions.
• Passwords can be used to identify
network managers.
Stand-alone encryption systems that pro-
vide the same protection are expensive
and relatively difficult to implement, and
can adversely affect network performance.
